Flexibly applied to various applications
Combination of functions,
Easy to achieve speed measurement, long measuring function, the single pulse output, the ratio of the set / distribution output, PWM control, cam switch control, such as a wide range of control LD77MH4 PDF LD77MH4
Single pulse.
To trigger the input as a starting point, with a minimum 25ns unit to adjust the ON/OFF time.
The action time deviation of ON/OFF is ns level, so it can achieve high precision control LD77MH4 PDF.
Velocity measurement and length measurement
In addition to the measurement of ON width and OFF width,
Can also achieve different sensor ON time difference and other conditions of the measurement.
The high precision measurement of the smallest 25ns unit can be realized.
Delayed output
The output time delay of each channel can be adjusted so that the error output can be realized LD77MH4 PDF. Number of input channels: 4ch.

Reduce the programming time.
The digital output value can be easily converted (zoom) to any number of functions without the program.
No need to use ladder diagram conversion program, can reduce the programming time.
Zoom setting example (L60AD4-CM).
The digital output value (20000 ~ 0) of the input range 20mA ~ 4mA is scaled to the value of positive and negative 20000.
Digital filter function
Simply set the parameters, you can eliminate the functtion of the redundant frequency components LD77MH4 datasheet.
Can be selected from low pass filter, high pass filter, medium pass filter.
No need to filter the ladder, can reduce programming time.
In addition, the conversion value of the A/D convertted by the filter can be obtained at the same time,
Therefore, the total processing time from the conversion to the filter processing can be shortened LD77MH4 datasheet.
